I have long hair and I refrain from cutting my hair after I came to know that for women it is impermissible to cut their hair. I observe hijab Alhumdulilah and I was wanting to have a nice hair cut not for any other purpose just because I want to have a nice hair cut once. Will it be permissible to cut my hair or is it haram?
